Explain the following relationship: One of the most remarkable aspects of life is its capacity not only continuously to seek states of dynamic equilibrium in relation to environment but also to produce remarkably faithful copies of itself for countless generations.

Dominant allele is the allele that determines the phenotypical features apparent in homozygous or heterozygous genotypes. What is the difference between homozygosity and heterozygosity?

What is the difference between a dominant allele and a recessive allele? Homozygosity occurs when an individual has two identical alleles of a gene, for example, AA or aa.

A gene is a sequence of DNA nucleotides that codifies the production of a protein. A recessive allele can remain hidden because it is not manifest in the heterozygous individual, meaning that it may be present in the genotype but is not expressed in the phenotype.
